## Linear Programming Class 12 MCQs Questions with Answers

Don’t forget to practice the multitude of MCQ Questions on Linear Programming Class 12 with answers so you can apply your skills during the exam.

Question 1.
The point which does not lie in the half plane 2x + 3y -12 < 0 is
(a) (1, 2)
(b) (2, 1)
(c) (2, 3)
(d) (-3, 2).

Hint:
Putting (2, 3) in 2x + 3y – 12.
Which becomes:
2(2)+ 3(3) – 12 = 4 + 9 – 12 = 1 > 0 and not ≤ 0.

Question 2.
The corner points of the feasible region determined by the following system of linear inequalities:
2x + y ≤ 10, x + 3y ≤ 15, x, y ≥ 0 are (0, 0), (5, 0), (3, 4) and (0, 5).
Let Z = px + qy, where p, q > 0. Conditions on p and q so that the maximum of Z occurs at both (3, 4) and (0, 5) is
(a) p = 3q
(b) p = 2q
(c) p = q
(d) q = 3p.

Question 3.
The corner points of the feasible region determined by the system of linear constraints are (0, 10), (5, 5), (15, 15), (0, 20). Let Z = px + qy, where p, q > 0. Condition on p and q so that the maximum of Z occurs at both the points (15, 15) and (0, 20) is
(a) p = q
(b) p = 2q
(c) q = 2p
(d) q = 3p.

The feasible solution for a LPP is shown in the following figure. Let Z = 3x – 4y be the objective function. Minimum of Z occurs at:
(a) (0, 0)
(b) (0, 8)
(c) (5, 0)
(d) (4, 10).

Question 5.
The corner points of the feasible region determined by the system of linear constraints are (0, 10), (5, 5), (15, 15), (0, 20). Let Z = px + qy, where p, q> 0. Condition on p and q so that the maximum of Z occurs at both the points (15, 15) and (0, 20) is Maximum of Z occurs at:
(a) (5, 0)
(b) (6, 5)
(c) (6, 8)
(d) (4, 10).
